Abstract: A polarizing film, wherein transparent protective films are laid, respectively, on/over both surfaces of a polarizer to interpose an adhesive layer (a) and an adhesive layer (b), respectively, between both surfaces of a polarizer, and transparent protective films. The adhesive layer (a) on/over one of both the surfaces has a glass transition temperature of −60° C. or higher and lower than 40° C. The adhesive layer (b) on/over the other surface has a glass transition temperature of 40° C. or higher. The adhesive layer (a) is a layer formed in the form of a cured product layer yielded by radiating an active energy ray to an active-energy-ray-curable adhesive composition (a). The active-energy-ray-curable adhesive composition (a) comprises, as radical polymerizable compounds, a component A having a logPow of −2 to 2, and a component B having a logPow more than 7, these logPow values being each an octanol/water distribution coefficient.

Abstract: An active-energy-ray-curable adhesive composition comprises at least radical polymerizable compounds. The radical polymerizable compounds comprise a component A having a log Pow of −2 to 2, and a component B having a log Pow more than 7, each of these log Pow values representing an octanol/water distribution coefficient. The component A preferably comprises at least one nitrogen-containing monomer selected from the group consisting of (meth)acrylamide derivatives, amino-group-containing monomers, and nitrogen-containing and heterocycle-containing vinyl monomers. The component B preferably comprises an alkyl (meth)acrylate having 18 to 20 carbon atoms.

Abstract: There is provided a polarizer protective film excellent in both bending resistance and adhesiveness with a polarizer. A polarizer protective film according to an embodiment of the present invention includes: an acrylic resin; and reinforcing particles dispersed in the acrylic resin. The reinforcing particles have flat shapes, and have a length-to-thickness ratio of 7.0 or less.
